If you have been enjoying playing Call of Duty : Black Ops 2 but have a few questions about certain mechanics within the game. Such as can you survive a semtex grenade? Or Can you stick C-4 to the train on Express and detonate it later to get a kill?

Most of your questions should be answered in the great Black Ops 2 Mythbusters videos which have been put together by Defend the House. Watch all four episodes after the jump.

Don’t forget to try out what yu have learnt in game, to amaze your team mates with ultra kills and saves, while in the heat of combat. Enjoy!
